Never gonna happen. There was NO history of racial bias claims on the part of Mr. Thorton--either to the company or the union--either one of which would have come down on even the most innocuous of claims like a ton of bricks.
Nope--he got caught, he knew he was gonna get shitcanned, he tried to set the stage. Family is gonna get laughed out of court, assuming it ever gets that far. There was no paper trail on the race allegations, and frankly, in this day and age, there WOULD have been. Period.
